Even with a traditional backup, you likely have to rebuild the server from scratch, reinstall Sage, wait hours/days for MS updates to complete, etc etc. Down time is probably 2 days or more. This is why the only way to go for a business is true snapshot virtualization (like Eversafe), this way there is 0 downtime, and getting the original server 'back together' is < 1 hour versus days (and many thousands in professional services fees and overtime fees)
